In Firefox, alert displayed just before blurring an element dispatches
the native blur event twice which tripped the jQuery logic if a jQuery blur
handler was not attached before the trigger call.
This was because the `leverageNative` logic part for triggering first checked if
setup was done before (which, for example, is done if a jQuery handler was
registered before for this element+event pair) and - if it was not - added
a dummy handler that just returned `true`. The `leverageNative` logic made that
`true` then saved into private data, replacing the previous `saved` array. Since
`true` passed the truthy check, the second native inner handler treated `true`
as an array, crashing on the `slice` call.
The same issue could happen if a handler returning `true` is attached before
triggering. A bare `length` check would not be enough as the user handler may
return an array-like as well. To remove this potential data shape clash, capture
the inner result in an object with a `value` property instead of saving it
directly.
Since it's impossible to call `alert()` in unit tests, simulate the issue by
replacing the `addEventListener` method on a test button with a version that
calls attached blur handlers twice.

Some browser extensions, like React DevTools, send messages to the content area.
Since our beforeunload event test listens for all messages, it used to catch
those as well, failing the test.
Add a `source` field to the payload JSON and check for it before treating the
message as coming from our own test to make sure the test passes even with such
browser extensions installed.

- Add the ability to retry by restarting the worker and
getting a different browser instance, after all

be successful when a refresh is not.

This is a complete rework of our testing infrastructure. The main goal is to modernize and drop deprecated or undermaintained dependencies (specifically, grunt, karma, and testswarm). We've achieved that by limiting our dependency list to ones that are unlikely to drop support any time soon. The new dependency list includes:
- `qunit` (our trusty unit testing library)
- `selenium-webdriver` (for spinning up local browsers)
- `express` (for starting a test server and adding middleware)
- express middleware includes uses of `body-parser` and `raw-body`
- `yargs` (for constructing a CLI with pretty help text)
- BrowserStack (for running each of our QUnit modules separately in all of our supported browsers)
- `browserstack-local` (for opening a local tunnel. This is the same package still currently used in the new Browserstack SDK)
- We are not using any other BrowserStack library. The newest BrowserStack SDK does not fit our needs (and isn't open source). Existing libraries, such as `node-browserstack` or `browserstack-runner`, either do not quite fit our needs, are under-maintained and out-of-date, or are not robust enough to meet all of our requirements. We instead call the [BrowserStack REST API](https://github.com/browserstack/api) directly.
**BrowserStack**
- automatically retries individual modules in case of test failure(s)
- automatically attempts to re-establish broken tunnels
- automatically refreshes the page in case a test run has stalled
- Browser workers are reused when running isolated modules in the same browser
- runs all browsers concurrently and uses as many sessions as are available under the BrowserStack plan. It will wait for available sessions if there are none.
- supports filtering the available list of browsers by browser name, browser version, device, OS, and OS version (see `npm run test:unit -- --list-browsers` for more info). It will retrieve the latest matching browser available if any of those parameters are not specified. Supports latest and latest-\d+ in place of browser version.
- cleans up after itself (closes the local tunnel, stops the test server, etc.)
- Requires `BROWSERSTACK_USERNAME` and `BROWSERSTACK_ACCESS_KEY` environment variables.
**Selenium**
- supports running any local browser as long as the driver is installed, including support for headless mode in Chrome, FF, and Edge
- supports running `basic` tests on the latest [jsdom](https://github.com/jsdom/jsdom#readme), which can be seen in action in this PR (see `test:browserless`)
- Node tests will run as before in PRs and all non-dependabot branches, but now includes tests on real Safari in a GH actions macos image instead of playwright-webkit.
- can run multiple browsers and multiple modules concurrently
Other notes:
- Stale dependencies have been removed and all remaining dependencies have been upgraded with a few exceptions:
- `sinon`: stopped supporting IE in version 10. But, `sinon` has been updated to 9.x.
- `husky`: latest does not support Node 10 and runs on `npm install`. Needed for now until git builds are migrated to GitHub Actions.
- `rollup`: latest does not support Node 10. Needed for now until git builds are migrated to GitHub Actions.
- BrowserStack tests are set to run on each `main` branch commit
- `debug` mode leaves Selenium browsers open whether they pass or fail and leaves browsers with test failures open on BrowserStack. The latter is to avoid leaving open too many sessions.
- This PR includes a workflow to dispatch BrowserStack runs on-demand
- The Node version used for most workflow tests has been upgraded to 20.x
- updated supportjQuery to 3.7.1

If the iframe is not initially visible, the `scrollboxSize` support test is
failing. jQuery then cached this value and and applied the wrong result
undefinitely.
This breaks jQuery UI's Dialogs inside initially invisible iframes.

Build was already happening in scripts like `test:browser` but those scripts
were missing `pretest`, meaning that running `npm install && npm test:browser`
may have failed if `pretest` wasn't run before or if its results were out of
date.
Even worse, with such stale data some tests may erroneously succeed.
This also removes a separate `pretest` step from GitHub Actions as it's no
longer needed.

Summary of the changes:
* Tests: Remove legacy jQuery.cache & oldIE leftovers
* Tests: Reformat JavaScript in delegatetest.html
* Docs: "jQuery Foundation Projects" -> "jQuery Projects"
* Tests: Drop an unused localfile.html file (modern browsers don't support
the `file:` protocol this way, there's no point in keeping the file around)
* Effects: Remove a redundant `!fn` check (`fn || !fn && easing` is equivalent
to `fn || easing`; simplify the code)
* CSS: Explain the fallback to direct object access in curCSS better
* Tests: Deduplicate `jQuery.parseHTML` test titles
* Dimensions: Add a test for fractional values
* Tests: Fix a buggy WebKit regex

Summary of the changes:
* expand `node_smoke_tests` to test the full & slim builds
* run `compare_size` on all built minified files; don't run it anymore on
unminified files where they don't provide lots of value
The main goal of this change is to make it easier to compare sizes of both the
full & slim builds between the `3.x-stable` & `main` branches.

Bootstrap 5 includes the following CSS on the page:
```css
*,
*::before,
*::after {
box-sizing: border-box;
}
```
That threw our `reliableTrDimensions` support test off. This change fixes the
support test and adds a unit test ensuring support test values on a page
including Bootstrap 5 CSS are the same as on a page without it.
Fixes gh-5270

Both IE & Edge Legacy need the workaround of calling `setDocument()` in an
`unload` handler to avoid "permission denied" errors. However, due to not being
possible to feature-detect this issue, the handler has been applied in all
browsers for windows different than the one in which jQuery was loaded.
jQuery 4.0, which drops Edge Legacy support, guards this workaround with
a `document.documentMode` check. This won't work in the 3.x line due to still
supporting Edge Legacy but we can check for
`document.documentElement.msMatchesSelector` instead as that API is
supported in IE 9+ and all Edge Legacy versions.
